The Modify URL option is a specialized header replacement that only matches the URL in the HTTP headers and replaces it with the one specified. This can be used on the client header going to the server.

Rule Name

This field is used for identification and should be named to help remember what the rule does in the Virtual Service.

Match String

Enter a pattern to match against the URL. If the URL matches the pattern, the URL value will be replaced. This follows regular expression rules.

Modified URL

Enter the new URL to be sent to the server. Regular expressions and back references can be used here to reuse part of the existing value.

Perform if Flag is Set

Only execute this rule if the specified flag is set.

The flag will have been set by a different rule.

Perform If Flag is NOT Set

Only try to execute this rule if the specified flag is not set.

Note: As of LoadMaster firmware version 7.2.51, you can assign URL modification rules to a response.
